I wonder what would happen if South Korea simply said they weren’t at war anymore. Acknowledge that yes, North Korea considers them at war with us. However, we consider us to be peaceful neighbours.

Whenever North Korea threatens them, simply reply with how sorry you are their brother nation feels this way, and you wish them a peaceful and successful future.

Leave the DMZ intact of course, but just unilaterally declare you are not actually at war and have nothing but brotherly love for them.

It's not the South Koreans per se that they have a problem with - it's the presence of the US military in South Korea that is seen as the real threat to North Korea. So if the South Koreans honestly want to repair their relation with the North Koreans, they will, at the very least, have to ask the Americans to leave. But the Americans will not leave because they have a hostile relation with the North Koreans, and they believe their presence in South Korea is the only thing preventing the North Koreans from throwing a few nukes at them. China and Russia will also not allow the North Koreans to repair their relations with the South Koreans unless they have guarantees from South Korea that they will be mindful of Chinese and Russian security concerns (which, in realpolitik terms would require South Korea to cut of ties with the US military and becoming "neutral").
